This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 24 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eglc To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Official Met Office and Heathrow observations confirmed a daily maximum of 22°C in London on August 24, aligning precisely with the average high of 22.6°C for the date and pre-event model consensus under stable high pressure and light northeasterly flow. This outcome produced near-certain market pricing at 22°C because no hourly readings or alternative stations approached 23°C, and post-event verification closed any realistic window for revision. A shift to 23°C would have required either an unverified urban heat-island spike exceeding official network data or a late model run showing sustained warmer advection—neither of which materialized.
